The National Institutes of Health standardized animal care equipment is presented in this catalog. Each piece of equipment is illustrated and described in terms of overall dimensions, construction, and general usage. A price list is included to estimate costs in budgeting, planning, and requisitioning animal care equipment. The standards and specifications covering the equipment provide for complete interchangeability within caging systems and related accessories without losing the flexibility to permit deviations and options to satisfy special requirements.
